2007 Mercedes-Benz E-Class Powertrain & Transmission Problems

AT ABOUT 87,000 MILES, THE CAR IS ESSENTIALLY USELESS BECAUSE OF A KNOWN DEFECT. THE BALANCE SHAFT, ENGINE INTAKE MANIFOLD AND TRANSMISSION CONDUCTOR PLATE NEED TO BE REPLACED. MERCEDES WILL NOT TAKE RESPONSIBILITY EVEN THOUGH THERE WAS A CLASS ACTION LAWSUIT.

THE ENGINE DIES SUDDENLY WHILE DRIVING. CAUSE UNKNOWN. CAR WILL RESTART WITHOUT TROUBLE, BUT THE SUDDENNESS OF THE PROBLEM IS REALLY STARTLING AND COULD BE VERY DANGEROUS ON THE FREEWAY OR ON A WINDING ROAD AT SPEED.

HIGHWAY DRIVING, CRUISE CONTROL SET. CRUISE CONTROL BEEPED, DISENGAGED. CAR CONTINUED TO DRIVE NORMALLY UNTIL I HAD TO STOP FOR A LIGHT. WHEN LIGHT CHANGED TO GREEN, THE CAR WOULD BARELY MOVE - HAD NO POWER, EVEN THOUGH THE RPMS SHOWED THE ENGINE RUNNING. FORTUNATELY, I WAS NEAR A GAS STATION AND WAS ABLE TO GET OFF THE ROAD. THIS COULD HAVE BEEN VERY HAZARDOUS HAD IT OCCURRED IN HEAVY TRAFFIC.... I PULLED OFF THE ROAD, RESTARTED THE CAR AND EVERYTHING SEEMED TO BE FINE. BUT THIS CAR BASICALLY LEFT ME SITTING IN THE MIDDLE OF THE ROAD AND COULD HAVE CAUSED A SERIOUS ACCIDENT IF SOMEONE HAD BEEN APPROACHING ME FROM THE REAR, OR IT WAS IN THE INTERSECTION AT THE TIME.

WHILE DRIVING ON FREEWAY, ENGINE SUDDENLY REVVED HIGH AND ALMOST RED-LINED ON RPM GAUGE. EXITED FREEWAY AND RPM (WHILE LOWERED) WAS STILL HIGH. A 3RD PARTY MECHANIC DIAGNOSED TRANSMISSION VALVE BODY FAILURE AND ADVISED ON REPLACEMENT. THIS MUST BE A A KNOWN ISSUE BECAUSE MECHANIC ASKED THAT IN ORDER TO REPLACE THE PART A VALID PERSONAL ID MUST BE RECORDED AS PART OF THE PARTS REPLACEMENT PER MERCEDES.

TRANSMISSION VIOLENTLY DOWNSHIFT SEVERAL GEARS WITHOUT WARNING .THIS CAUSES SKIDDING, THROWING OCCUPANTS VIOLENTLY TOWARD THE WIND SHIELD THIS HAPPENS WHEN AUTO IS IN DRIVE WITH SPEEDS BETWEEN 40-45 MPH. THIS UNEXPECTED LURCHING CAUSES LOSS OF CONTROL ON WET AND DRY PAVEMENT. THIS DEFECT HAS BEEN REPORTED TO MERCEDES BENZ WITH NO CORRECTIVE ACTION OFFERED.

THE AUTOMATIC TRANSMISSION WOULD NOT SHIFT PROPERLY. VERY DANGEROUS. IT IS A SEVEN SPEED AUTOMATIC TRANSMISSION BUT SEEMED TO STAY IN A HIGH GEAR SO THE VEHICLE DID NOT ACCELERATE. IT WOULD NOT GO INTO REVERSE. IT OCCURRED ON A MAJOR HIGHWAY. THE ME DEALER SAID THE REPAIR WILL BE ABOUT $2300 THIS SHOULD BE A RECALL. SAFETY HAZARD.

30 AUG.16 TOOK MY 07 E350 WITH 29427 MILES TO THE DEALERSHIP BECAUSE THE CHECK ENGINE LIGHT CAME ON AND THE CAR WAS HARD STARTING. AFTER ARRIVING I INFORMED THE SERVICE WRITER THE CAR HAD SHUT DOWN WHILE DRIVING. WE WERE PROCEEDING THROUGH A BUSY MAJOR INTERSECTION WHEN THE CAR SHUT DOWN. LUCKILY IT STARTED SO WE COULD SAFELY EXIT THE BUSY MAJOR INTERSECTION. AFTER A DIAGNOSTIC TEST WAS RAN, I WAS INFORMED THE CRANKSHAFT HALL SENSOR WAS DEFECTIVE. ADDITIONALLY, THE ENGINE CONTROL UNIT, ENGINE WIRING HARNESS, CRANK SENSOR AND VARIOUS OTHER COMPONENTS ARE OIL SOAKED. I NOTIFIED MERCEDES BENZ TO BE TOLD THE CAR WAS OUT OF WARRANTY. MERCEDES BENZ SHOULD BE HELD ACCOUNTABLE FOR THE UNSAFE DEFECTIVE MATERIALS THEY USE. THE ABOVE ISSUES ARE A DANGER TO THE OCCUPANTS AND GENERAL PUBLIC AS WELL. THE DEFECTIVE OIL SOAKED WIRING HARNESS IS CAN CAUSE A FIRE. THE CAR SHUTS DOWN WHILE DRIVING IS DANGEROUS.

IN 2011, I PURCHASED MY VEHICLE FROM A DEALERSHIP AS CERTIFIED/PREOWNED AT 46,717 MILES. REGULAR MAINTENANCE WAS KEPT UP AT THE DEALERSHIP. IN 2015 AT 74,563 MILES, I BROUGHT MY VEHICLE IN FOR 2 PROBLEMS: A CHECK ENGINE LIGHT HAD COME "ON" AND MY VEHICLE WAS EXPERIENCING VIBRATIONS FROM THE POWER TRAIN WHEN TURNING AND SHUDDERING WHEN MAKING SHARP TURNS AT LOW SPEEDS. THE CHECK ENGINE LIGHT WAS A RESULT OF A BALANCE SHAFT ENGINE PROBLEM WHICH WAS, AT THE TIME, IN A CLASS ACTION SUIT REGARDING THIS PROBLEM FOR THESE VEHICLES. THE MANUFACTURER AGREED TO PAY A PORTION OF MY REPAIR FOR THE BALANCE SHAFT ISSUE. THE SECOND PROBLEM TURNED OUT TO BE A TRANSFER CASE ISSUE. THE DEALERSHIP STATED I HAD A BAD TRANSFER CASE AND THEY RECOMMENDED I HAVE THE TRANSFER CASE REPLACED. AT THE TIME, I COULD ONLY BUDGET MYSELF FOR THE BALANCE SHAFT REPAIR AND 4 NEW TIRES. THE TRANSFER CASE OIL WAS CHANGED WHICH SLIGHTLY IMPROVED THE VIBRATION/SHUDDERING ISSUE. I CURRENTLY STILL HAVE THIS ISSUE MORE SEVERELY AND REQUIRE THE TRANSFER CASE BE REPLACED. MY VEHICLE'S TRANSFER CASE OIL WAS CHANGED AT 30K MILES BY THE PREVIOUS OWNER. THROUGH RESEARCH, I HAVE DISCOVERED THAT IN JANUARY 2009, A MANUFACTURER BULLETIN CAME OUT THAT SPECIFIED MY VEHICLES VIN NUMBER WAS INCLUDED IN THE STATED PROBLEMS WITH THE TRANSFER CASE. THEY HAD INSTALLED DEFECTIVE TRANSFER CASES AT PRODUCTION IN 2007 AND SHOULD REMEDY THIS! I HAVE SPOKEN TO THE MANUFACTURER AND THEY WILL ONLY PAY 25% OF MY PARTS FOR THIS REPAIR WHICH LEAVES ME WITH A $3200 BILL FOR A PROBLEM THEY KNEW ABOUT. ON MANY OCCASIONS, WHILE WAITING FOR MY VEHICLE TO HAVE MAINTENANCE COMPLETED, I OVER HEARD SERVICE REPRESENTATIVES SPEAKING TO OTHER CUSTOMERS BY PHONE OR IN PERSON. THE SERVICE REPS INDICATED IN MANY INSTANCES THAT THE PROBLEM THE CUSTOMER WAS HAVING WITH THEIR VEHICLE WAS DUE TO THE TRANSFER CASE. THESE TRANSFER CASES SHOULD BE RECALLED!

UPON EXITING THE FREEWAY AND COMING TO A COMPLETE STOP, VEHICLE WAS UNABLE TO ACCELERATE AS USUAL. ACCELERATION WAS VERY SLOW AND WITHOUT POWER. UPON LOOKING AT GAUGE CLUSTER, THE VEHICLE SHIFTED ITSELF INTO 5TH GEAR IT SEEMS. USING THE PADDLE SHIFTER I THEN PROCEEDED TO DOWNSHIFT THE TRANSMISSION TO 1ST GEAR TO PULL AWAY FROM STOP. CAR REMAINED IN AUTOMATIC MODE, BUT WAS NOT SHIFTING OUT OF GEAR. CLUSTER DISPLAYS AUTOMATIC COMFORT MODE, BUT WOULD NOT LEAVE FROM WHAT IT SEEMS 2ND GEAR. STOP ENGINE AND RESTART CAR, DRIVE AROUND AND CAR WILL NOT SHIFT OUT OF GEAR. UPON SEARCHING THE INTERNET THIS IS A VERY VERY COMMON ISSUE WITH ALL 7 SPEED AUTOMATIC TRANSMISSIONS OFFERED BY MERCEDES BENZ. THEY HAVE NOT ASSUMED RESPONSIBILITY FOR A DEFECT IN PART. MANY HAVE SPENT THOUSANDS OF DOLLARS DIAGNOSING AND REPAIRING TRANSMISSION RELATED ISSUES WHICH REVOLVE AROUND THIS SUB PAR TRANSMISSION. IF YOU SEARCH ONLINE FOR CONDUCTOR PLATE, MERCEDES YOU WILL FIND COUNTLESS PEOPLE WHO HAVE BEEN DEALING WITH TRANSMISSION FAILURE'S DUE TO THIS FAULTY PART. THIS ISSUE AFFECTS ALL MERCEDES 7 SPEED TRANSMISSIONS AND AS SEEN THROUGH ONLINE SEARCH IS A WORLD WIDE ISSUE. I HAVE READ ABOUT THIS IN THE UK, AUSTRALIA, SOUTH AMERICA, AS WELL AS IN THE USA. *TR

TRANSMISSION. IT IS MY UNDERSTANDING THAT THIS YEAR AND MODEL CAR HAS KNOWN TRANSMISSION PROBLEMS. *TR

TL* THE CONTACT OWNS A 2007 MERCEDES BENZ E230. THE CONTACT STATED THAT WHEN ATTEMPTING TO ACCELERATE, THE VEHICLE FAILED TO SHIFT FROM FIRST GEAR AND THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 65,000.

CHECK ENGINE LIGHT CAME ON. TOOK THE VEHICLE TO THE LOCAL DEALER AND THEY FOUND CODES 1200, 1208, P0016 AND P0017. WORN BALANCE SHAFT SPROCKET. DOING RESEARCH ONLINE TURNS OUT THERE ARE HUNDREDS AND HUNDREDS OF AFFECTED MB CUSTOMERS. MERCEDES KNEW OF THIS PROBLEM AS EARLY AS 2007 BUT HAS NOT PUBLICLY ADDRESSED THIS ISSUE OR ISSUED A RECALL. THE BILL TO FIX THIS ISSUE IS OVER $4,000, SOME PEOPLE REPORT THE DEALER QUOTING THEM OVER $10,000. MY PRICE TO FIX THIS IS $5,995. MY COMPLAINT IS THAT THIS IS A KNOWN ISSUE BY MERCEDES. KNOWINGLY THEY INSTALLED, AND KEPT INSTALLING, PARTS THAT WEAR OUT PREMATURELY LEAVING CUSTOMERS WITH AN UNFAIRLY LARGE BILL TO CORRECT THEIR MISTAKE. *TR

TRANSMISSION DOES NOT DOWNSHIFT WHEN YOU TRY TO STOP, IT CHOKES AND DIES. TRANSMISSION IS STUCK ON THE 3 GEAR AND DOES NOT DOWNSHIFT. *TR

THE FRONT INNER TIRES GET CUPPING OVER THE TIME, I HAVE TO REPLACE THEM EVERY 10,000 MILES. ALL THE SUSPENSION PARTS ARE NEW PUT STILL THE PROBLEM GOING ON. IT IS A MANUFACTURING PROBLEM WITH THE HEAVY ENGINE GET THE LOAD ON THE POWER TRAIN AND WITH THE TIME IT LOSING AND MAKE THE TIRES CUPPING FROM THE INNER SIDE.

I BOUGHT THIS CAR ABOUT 4 MONTHS AGO. THIS CAR HAS BEEN SERVICED RELIGIOUSLY AT THE LOCAL MERCEDES DEALER AND THERE HAS BEEN "NO KNOW PROBLEMS". ON A THURSDAY I NOTICED THE CAR SHIFTING A LITTLE FUNNY SO I HAD MY HUSBAND DRIVE IT JUST TO BE SURE. HE NOTICED THE SAME ERRATIC SHIFTING. ON SATURDAY I DROPPED THE CAR OFF AT THE MERCEDES DEALER (SAME DEALER IT HAS ALWAYS BEEN SERVICED AT). WHEN I PARKED THE CAR I WANTED TO CHECK EACH GEAR JUST TO MAKE SURE AND WHAT DO YOU KNOW...IT WOULD NOT SHIFT INTO REVERSE. LATER THAT DAY I HAD TO CALL MERCEDES TO FIND OUT WHAT WAS GOING ON WITH THE CAR AND THEY PROCEEDED TO TELL ME THE CAR HAD METAL SHAVINGS IN THE TRANSMISSION PAN AND WOULD NEED A NEW TRANSMISSION. THE QUOTE FOR A NEW TRANSMISSION IS $5800!!! I DON'T UNDERSTAND HOW THE CAR DID NOT GIVE ME ANY WARNING NOR AN INDICATOR LIGHT. THE CAR ONLY HAS 60K MILES ON IT AND IN NO WAY SHOULD NEED A NEW TRANSMISSION. ALSO, KEEP IN MIND THE TRANSMISSION WAS SERVICED AT THIS SAME MERCEDES DEALER AT 39K MILES. SOMETHING IS NOT RIGHT AND I WANT ANSWERS. I AM COMPLETELY SHOCKED AND SO UPSET. *TR

WHEN ACCELERATING FROM A STOP LIGHT, THE CAR WOULD NOT SHIFT GEARS AUTOMATICALLY. THE CAR SEEMS TO BE STUCK IN 1ST GEAR OR NEUTRAL AS I COULD NOT GET PAST 20MPH WITHOUT MAXING OUT MY RPM'S. I HAD TO DRIVE 3 MILES GOING 20MPH TO GET SOMEWHERE SO I COULD GET TOWED. AFTER TOWED TO THE DEALERSHIP, THEY COULD NOT REPLICATE THE SITUATION. THIS HAS HAPPENED TWICE WITHIN A WEEK'S TIME. THIS IS A MERCEDES 2007 E350. I HAVE SEEN OTHER POSTS ABOUT THIS EXACT SAME THING WITH NO SOLUTION. THE DEALERSHIP SAID TO PULL OVER AND RESTART THE CAR. WHAT!!! WHAT KIND OF FIX IS THAT? I DO THAT TO MY HOME PC...I SHOULDN'T HAVE TO DO THAT FOR MY CAR! I BOUGHT THIS CAR LESS THAN 30 DAYS AGO...AND THE DEALERSHIP DOESN'T SEEM TO WANT ANY PART OF IT. I HAVEN'T EVEN MADE THE FIRST PAYMENT OR RECEIVED MY PERMANENT TAGS YET. *TR

THE CHECK ENGINE LIGHT CAME ON AND THE ENGINE STARTED MAKING A "CLICKING" NOISE. I TOOK THE CAR TO THE MERCEDES DEALERSHIP AND THEY SAID THAT THE BALANCE SHAFT GEAR WAS COMPLETELY DETERIORATED. THEY DESCRIBED THE GEAR AS "CHEWED UP"! I HAD NO CHOICE BUT TO PAY $4,000.00 TO GET THE ENGINE REMOVED FROM MY CAR AND HAVE THE BALANCE SHAFT REPLACED. *TR
